The main display regions 190 a 1, 190 a 2, and 190 a 3 may be distinguished from the edge display region 190 b and 190 c with respect to virtual lines 190 b 1 and 190 c 1. The virtual lines 190 b 1 and 190 c 1 may mean lines where the curvatures of the main display regions 190 a 1, 190 a 2, and 190 a 3 start to be modified. The virtual lines 190 b 1 and 190 c 1 may mean lines where the curvatures of the main display regions 190 a 1, 190 a 2, and 190 a 3 are changed to the curvatures of the edge display regions 190 b and 190 c. The virtual lines 190 b 1 and 190 c 1 may mean lines where the curvatures of the main display regions 190 a 1, 190 a 2, and 190 a 3 are changed to one of the single curvature of the edge display regions 190 b and 190 c and a first curvature of the multi-curvature.

The curvatures of the edge display regions 190 b and 190 c may include one of the single curvature and the multi-curvature. Regarding the edge display regions 190 b and 190 c, the single curvature may mean the edge display regions 190 b and 190 c having one curvature. For example, the single curvature may be equal to or greater than 13R and equal to or less than 5R. Cross-sections on respective sides of the electronic device including edge display region 190 b and 190 c having a single curvature may include a semicircular form and an oval form.

The multi-curvature of the edge display regions 190 b and 190 c may mean that the first curvature corresponding to the region including virtual lines (including 190 b 1 and 190 c 1) extended from the main display regions 190 a 1, 190 a 2, and 190 a 3 and bent may be different from the second curvature corresponding to a region (e.g., including corner regions 190 b 2 and 190 c 2 of the edge display regions 190 b and 190 c) contacting a bezel on the front.

For example, the first curvature may be 12R or 13R. The first curvature may be equal to or greater than 13R and equal to or less than 5R. Further, the second curvature may be 6.5R or 6.9R. The second curvature may be equal to or greater than 8R and equal to or less than 4R. The cross-sections of the respective sides of the electronic device including edge display regions 190 b and 190 c with a multi-curvature may include a semicircular form or an oval form.

A curvature of the left edge display region 190 b may be different from a curvature of the right edge display region 190 c. When the edge display regions 190 b and 190 c have a single curvature, for example, the curvature of the left edge display region 190 b may be 13 R. Also, the curvature of the right edge display region 190 c may be 6.5R.

One of the edge display regions 190 b and 190 c may have a single curvature, and the other may have a multi-curvature. For example, the left edge display region 190 b may have a single curvature, and the right edge display region 190 c may have a multi-curvature. The single curvature of the left edge display region 190 b may be 13 R, and the first curvature of the right edge display region 190 c may be 12R and the second curvature thereof may be 6.5R.

In an example embodiment, the single curvature value and/or the multi-curvature value are examples and are not limited thereto. It will be easily understood by a person skilled in the art that the single curvature value and/or the multi-curvature value are modifiable.

The main display regions 190 a 1, 190 a 2, and 190 a 3 may be divided into a first display region 190 a 1 and second display regions 190 a 2 and 190 a 3 with respect to virtual lines 190 b 3 and 190 c 3. The virtual lines 190 b 3 and 190 c 3 may mean lines that are separated from the virtual lines 190 b 1 and 190 c 1 by a predetermined length. The second display regions 190 a 2 and 190 a 3 may mean regions that are provided near the edge display regions 190 b and 190 c from among the main display regions 190 a 1, 190 a 2, and 190 a 3.

For example, the edge display panel 191 may include a liquid crystal display (LCD), a light emitting diode (LED), and an organic light emitting diode (Organic LED). The edge display panel 191 may display various images and a plurality of objects according to various operational states of the electronic device 100 and executions of applications or services.

Referring back to FIG. 1, the edge photo sensor 193 is a sensor for receiving light of a desired (or, alternatively, a predetermined) wavelength, and it may include a plurality of sensor pixels that include an organic photodiode and a photo transistor. The sensor pixel may be divided into a first sensor pixel for receiving light of a near infrared ray wavelength (substantially 780 nm to 1,500 nm) and a second sensor pixel for receiving light of a red wavelength (substantially 625 nm to 740 nm).

In an example embodiment, a touch is not limited to contacts of the body of the user or the input pen 167 on the edge touch screen 190, and it includes a non-contact. For example, the non-contact may include a hovering with a gap between the edge touch screen 190 and the body of the user or the input pen 167 that is equal to or less than 50 mm. It will be easily understood by a person skilled in the art that the detectable non-contact gap on the edge touch screen 190 is modifiable according to the performance or structure of the electronic device 100.

The edge touch screen controller 197 converts an analog signal corresponding to the single touch or the multi-touch received from the edge touch panel 195 into a digital signal, and transmits the same to the controller 110. The controller 110 may calculate an X coordinate and a Y coordinate corresponding to a touching position of the touch input by the edge touch panel 195 by using the digital signal received from the edge touch screen controller 197. Further, in the case of the electromagnetic resonance type edge touch screen, an electromagnetic resonance type edge touch screen controller (not shown) may be used.

The controller 110 may control the edge touch screen 190 by using the digital signal received from the edge touch screen controller 197. For example, the controller 110 may display the shortcut icon displayed on the edge touch screen 190 corresponding to the input touch in a different manner from other shortcut icons or it may display an application screen to the edge touch screen 190 by performing an application (e.g., a telephone) corresponding to the selected shortcut icon.

The edge touch screen controller 197 may include one edge touch screen controller or a plurality of edge touch screen controllers. The edge touch screen controller 197 may be included in the controller 110 corresponding to the performance or structure of the electronic device 100. For example, in some example embodiments, the processor 111 of the controller 110 may be configured, through a layout design or execution of computer readable instructions stored in the ROM 112 and/or the RAM 113 as a special purpose computer to implement the edge touch screen controller 197.

The edge touch screen controller 197 may convert the analog signal corresponding to the touch received from the electromagnetic resonance type edge touch screen into a digital signal and may transmit the same to the controller 110, aside from the analog signal corresponding to the single touch or multi-touch received from the edge touch screen 190.

The edge touch screen controller 197 may control the red pixel and the near infrared ray pixel included in the edge display panel 191 to emit light. Further, the edge touch screen controller 197 may drive the edge photo sensor 193 to receive light around the edge touch screen 190.

After emitting the red pixel and the near infrared ray pixel included in the edge display panel 191, the edge touch screen controller 197 according to an example embodiment may analyze an optical signal acquired from a sensor pixel of the edge photo sensor 193 through blood vessels of the user to measure the heartbeat and saturation of peripheral oxygen (SpO2).

A method for controlling an electronic device 100 for measuring a heartbeat and/or a saturation of peripheral oxygen (SpO2) of a user by using the above-configured edge touch screen will now be described with reference to FIG. 10 and FIG. 11.

FIG. 10 shows a flowchart of a method for controlling an electronic device 100 according to an example embodiment.

Referring to FIG. 10, in operation S101, the controller 110 determines whether a touch input of the user of the edge touch screen 190 is sensed in the edge display regions 190 b and 190 c.

For example, when the user grasps the electronic device 100, the finger of the user may contact the edge display regions 190 b and 190 c of the edge touch screen 190. The touch sensor of the edge display regions 190 b and 190 c of the edge touch panel 195 detects the touch, and transmits a corresponding signal to the edge touch screen controller 197. The edge touch screen controller 197 transmits the touch signal provided by the edge touch panel 195 to the controller 110. When the touch signal is input, the controller 110 determines as that the touch input of the user is sensed. In other example embodiments, the edge touch screen controller 197 and the controller 110 may be embodied in the same controller such that the touch sensor transmits the corresponding signal directly to the controller 110.

In operation S103, the controller 110 may determine whether the touch input of the user in the edge display regions 190 b and 190 c is maintained. The controller 110 may determine whether the touch input of the user in the edge display regions 190 b and 190 c is maintained for a desired (or, alternatively, a predetermined) time (e.g., one second).

For example, the controller 110 may not start or may stop measuring of a heartbeat and/or a saturation of peripheral oxygen (SpO2) when a touch input of the user of the edge touch screen 190 is not provided or the touch input of the user in the edge display regions 190 b and 190 c is not maintained.

In contrast, when the finger of the user contacts the edge display regions 190 b and 190 c for one second as the user grasps the electronic device 100, the controller 110 may determine as that the touch input of the user is maintained and proceed to operation S105.

In operation S105, when the touch input of the user in the edge display regions 190 b and 190 c is maintained, the controller 110 instructs the near infrared ray pixel IRPX and the red pixel corresponding to the region on the edge display panel 1910 touched by the user to emit light. The controller 110 calculates a touch position of the touch input provided to the edge touch panel 195 and maintained.

For example, when the near infrared ray pixels IRPXs are provided in the edge display regions 190 b and 190 c, the controller 110 may instruct the near infrared ray pixels IRPXs provided near the touch position and provided in the edge display regions 190 b and 190 c to emit light. Further, when the near infrared ray pixels IRPXs are provided in the region 190 d corresponding to the light blocking member 1960, the controller 110 may instruct the near infrared ray pixel IRPX provided in a row provided near the touch position and provided in the region 190 d corresponding to the light blocking member 1960 to emit light. Also, when the near infrared ray pixels IRPXs are provided in the edge second display region 191 a 2, the controller 110 may instruct the near infrared ray pixel IRPX provided in a row provided near the touch position and provided in the second display region 191 a 2 to emit light. In addition, the controller 110 may combine the above-described example embodiments and instruct the near infrared ray pixel IRPX to emit light according to the position of the near infrared ray pixels IRPXs.

For example, when the red pixels are provided in the edge display regions 190 b and 190 c, the controller 110 may instruct the red pixels provided near the touch position and provided in the edge display region 190 b and 190 c to emit light. Further, when the red pixels are provided in the edge second display region 191 a 2, the controller 110 may instruct the red pixel provided near the touch position and provided in the second display region 191 a 2 to emit light. In addition, the controller 110 may combine the example embodiments and may instruct the red pixels to emit light according to the position of the red pixels.

Further, in addition to emitting light when the touch input of the user is determined to be maintained, the controller 110 may also notify the user of starting of measuring a heartbeat and/or a saturation of peripheral oxygen (SpO2) through an output unit 160 such as the edge touch screen 190, the speaker 163, and/or the vibration motor 164.

In addition, when the touch input of the user is determined to be maintained, the controller 110 may display an alert window for inquiring a start of measuring a heartbeat and/or a saturation of peripheral oxygen (SpO2) to the edge touch screen 190, and may receive a measurement start command or a measurement stop command from the user.

In operation S107, the controller 110 operates the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX corresponding to the region touched by the user to receive information from the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX. In some example embodiments, the information may be associated with an amount of reflected light received by the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX.

For example, when the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the edge display regions 190 b and 190 c, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided near the touch position and provided in the edge display region 190 b and 190 c. When the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the region 190 d corresponding to the light blocking member 1960, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided in a row provided near the touch position and provided in the region 190 d corresponding to the light blocking member 1960. When the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the edge second display region 191 a 2, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided in a row provided near the touch position and provided in the second display region 191 a 2. Besides this, the controller 110 may combine the example embodiments and may operate the sensor pixels SAPX and SBPX according to the position of the sensor pixels SAPX and SBPX.

In operation S109, the controller 110 measures a heartbeat and/or a saturation of peripheral oxygen (SpO2) of the user by using a change of an amount of light received by the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX.

The heartbeat may be measured by converting a blood flow change that is a volume change of peripheral blood vessels into a light amount change. The saturation of peripheral oxygen (SpO2) represents biometrics for indicating a content of oxygen that exists in the hemoglobin from among various components of the blood, and it may be measured by sequentially emitting the red light and the near infrared ray light through the red pixel and the near infrared ray pixel IRPX for each period to irradiate the same to a peripheral blood vessel part (e.g., a finger end) of the user, allowing the same to be reflected on the human body, receiving light by the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX, and observing the change of the amount of the received light. A method for measuring a heartbeat and a saturation of peripheral oxygen (SpO2) using near infrared ray light and red light is known to a person skilled in the art, so no description thereof will be provided.

In operation S111, the controller 110 outputs heartbeat and saturation of peripheral oxygen (SpO2) information to the edge touch screen 190 and/or the speaker 163, and stores the same in the storage unit 175.

The controller 110 may display heartbeat and saturation of peripheral oxygen (SpO2) information using the edge touch screen 190, and/or may output the heartbeat and saturation of peripheral oxygen (SpO2) information as a voice through the speaker 163.

Further, the controller 110 may store the heartbeat and saturation of peripheral oxygen (SpO2) information in the storage unit 175, and the user may check his health state in a later time.

In addition, the controller 110 may report the heartbeat and saturation of peripheral oxygen (SpO2) information to an external storage unit or a server through the mobile communicator 120 and the sub-communicator 130.

According to at least one of the example embodiments, the biometrics of the user may be conveniently measured without an additional module, so the inner space of the electronic device 100 may be efficiently used. Hence, the electronic device 100 may become slim or down-sized, and the effect of providing a new user experience to the user is generated.

FIG. 11 shows a flowchart of a method for an electronic device 100 according to another example embodiment.

Referring to FIG. 11, in operation S201, the controller 110 determines whether the touch input of the user of the edge touch screen 190 is sensed in a plurality of regions in the edge display regions 190 b and 190 c.

For example, when the user grasps the electronic device 100, the finger of the user may contact the left edge display region 190 b and the right edge display region 190 c of the edge touch screen 190. Respective touch sensors of the left edge display region 190 b and the right edge display region 190 c of the edge touch panel 195 may detect the touch, and transmit a corresponding signal to the edge touch screen controller 197. The edge touch screen controller 197 transmits the touch signal detected by the left edge display region 190 b and the touch signal detected by the right edge display region 190 c to the controller 110. When the touch signals corresponding to the touch in the left edge display region 190 b and the touch in the right edge display region 190 c, that is, the multi-touch in the respective edge display regions 190 b and 190 c are input, the controller 110 determines as that the touch input of the user is sensed in a plurality of regions in the edge display regions 190 b and 190 c.

In operation S203, the controller 110 determines whether the touch input of the user in a plurality of regions in the edge display regions 190 b and 190 c is maintained. The controller 110 may determine whether the touch input of the user in a plurality of regions in the edge display regions 190 b and 190 c are maintained for a desired (or, alternatively, a predetermined) time (e.g., one second).

For example, when the finger of the user contacts a plurality of regions in the edge display region 190 b and 190 c for one second in order for the user to grasp the electronic device 100, the controller 110 may determine as that the touch input of the user is maintained.

When the touch input of the user on the edge touch screen 190 is not provided or the touch input of the user in the edge display regions 190 b and 190 c is not maintained, the controller 110 does not start measuring the heartbeat and the saturation of peripheral oxygen (SpO2) or stops the same.

In operation S205, when the touch input of the user in a plurality of regions in the edge display regions 190 b and 190 c is maintained, the controller 110 instructs the near infrared ray pixel IRPX and the red pixel to emit light corresponding to the region touched by the user. For example, the controller 110 calculates a touch position of the touch input provided to the edge touch panel 195 and maintained. The controller 110 instructs the near infrared ray pixel IRPX and the red pixel of the touch input on the edge display panel 1910 to emit light.

For example, when the near infrared ray pixels IRPXs are provided in the edge display regions 190 b and 190 c, the controller 110 may instruct the near infrared ray pixels IRPXs provided near the touch position and provided in the edge display regions 190 b and 190 c to emit light. Also, the near infrared ray pixels IRPXs are provided in the region 190 d corresponding to the light blocking member 1960, the controller 110 may instruct the near infrared ray pixel IRPX provided in the row provided near the touch position and provided in the region 190 d corresponding to the light blocking member 1960 to emit light. Further, when the near infrared ray pixels IRPXs are provided in the edge second display region 191 a 2, the controller 110 may instruct the near infrared ray pixel IRPX provided in the row provided near the touch position and provided in the second display region 191 a 2 to emit light. In addition, the controller 110 may combine the example embodiments and instruct the near infrared ray pixel IRPX to emit light according to the position of the near infrared ray pixels IRPXs.

For example, when the red pixels are provided in the edge display regions 190 b and 190 c, the controller 110 may instruct the red pixels provided near the touch position and provided in the edge display regions 190 b and 190 c to emit light. Also, when the red pixels are provided in the edge second display region 191 a 2, the controller 110 may instruct the red pixel provided in the row provided near the touch position and provided in the second display region 191 a 2 to emit light. In addition, the controller 110 may combine the example embodiments and may instruct the red pixels to emit light according to the position of the red pixels.

When the touch input is determined to be maintained, the controller 110 may notify the user of starting of a measurement of the heartbeat and/or the saturation of peripheral oxygen (SpO2) through the output unit 160 such as the edge touch screen 190, the speaker 163, and/or the vibration motor 164.

In addition, when the touch input of the user is determined to be maintained, the controller 110 may display an alert window for inquiring a starting of measurement of the heartbeat and the saturation of peripheral oxygen (SpO2) to the edge touch screen 190, and may receive a measurement start command or a measurement stop command.

In operation S207, the controller 110 operates the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX corresponding to the region touched by the user to receive information from the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX. In some example embodiments, the information may be associated with an amount of reflected light received by the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX.

For example, when the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the edge display regions 190 b and 190 c, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided near the touch position and provided in the edge display regions 190 b and 190 c. When the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the region 190 d corresponding to the light blocking member 1960, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided in the row provided near the touch position and provided in the region 190 d corresponding to the light blocking member 1960. When the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX are provided in the edge second display region 191 a 2, the controller 110 may operate the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX provided in the row provided near the touch position and provided in the second display region 191 a 2. Besides this, the controller 110 may combine the example embodiments and may operate the sensor pixels SAPX and SBPX according to the position of the sensor pixels SAPX and SBPX.

In operation S109, the controller 110 measures the heartbeat and/or the saturation of peripheral oxygen (SpO2) of the user by using the change of the amount of light received by the near infrared ray sensor pixels SAPX and SBPX and the red sensor pixels SAPX and SBPX.

In operation S211, the controller 110 compares the heartbeat information measured by a plurality of regions in the edge display regions 190 b and 190 c, and compares the saturation of peripheral oxygen (SpO2) information measured in a plurality of regions in the edge display regions 190 b and 190 c.

In operation S213, when the heartbeat information and the saturation of peripheral oxygen (SpO2) information measured by a plurality of regions are similar to each other (e.g., within 5% of the deviation), the controller 110 outputs the measured heartbeat and saturation of peripheral oxygen (SpO2) information to the edge touch screen 190 or the speaker 163, and stores the same in the storage unit 175. In this instance, like a mean value of a plurality of heartbeat information and a middle value of a plurality of heartbeat information, one selected from among a plurality of heartbeat information is output and stored. In a like manner, like a mean value of a plurality of saturation of peripheral oxygen (SpO2) information and a middle value of a plurality of saturation of peripheral oxygen (SpO2) information, one selected from among a plurality of saturation of peripheral oxygen (SpO2) information is output and stored.

The controller 110 may display heartbeat and saturation of peripheral oxygen (SpO2) information to the edge touch screen 190, or may output the heartbeat and saturation of peripheral oxygen (SpO2) information as a voice through the speaker 163.

Further, the controller 110 may store the heartbeat and saturation of peripheral oxygen (SpO2) information in the storage unit 175, and the user may check his health state in a later time.

In addition, the controller 110 may report the heartbeat and saturation of peripheral oxygen (SpO2) information to an external storage unit or a server through the mobile communicator 120 and the sub-communicator 130.

When a plurality of heartbeat information and saturation of peripheral oxygen (SpO2) information measured by a plurality of regions are different from each other, in operation S215, the controller 110 notifies the user of a restarting of measurement of the heartbeat and the saturation of peripheral oxygen (SpO2) through the output unit 160 such as the edge touch screen 190, the speaker 163, and the vibration motor 164.

According to at least one of example embodiments, the biometrics of the user may be conveniently measured and it may be measured without an additional module, so the inner space of the electronic device 100 may be efficiently used. Hence, the electronic device 100 may become slim or down-sized, and the effect of providing a new user experience to the user is generated.
